Bed Bug Exterminator in Montreal

An infestation is rarely identified from a single clue. The most reliable signs are: bites in a line or in a cluster, itching especially on waking, small black spots (droppings) on sheets, mattress seams or baseboards, blood stains, shed skins (translucent casings) and sometimes a slightly sweet/musty smell in the case of an advanced infestation.

In Montreal, the risk goes up in multi-unit buildings (spread between units). The right reflex: confirm visually (seams, box springs, headboard, cracks, outlets, baseboards), avoid moving furniture from one room to another, and get an inspection quickly if you have any doubt.

A serious extermination follows a clear protocol: inspection, explanation to the client, preparation plan, targeted treatment, then follow-up. The exterminator treats the at-risk areas (bed frames, mattress/box spring edges, baseboards, cracks, harbourage areas) and gives you clear instructions: high-temperature washing/drying, reducing clutter, protecting linens and handling at-risk items.

The goal is to eliminate the infestation without improvising: you treat the hiding spots, not “at random”.

Because bed bugs and their eggs do not all react the same way to the first visit. A professional protocol calls for 2 treatments with Temprid SC (Bayer Canada), 21 days apart:

• Treatment 1: strongly reduces the active population and lays down a residual on the strategic areas.
• Treatment 2 (at 21 days): targets the ones that would have hatched after the first visit or the ones that would have avoided the initial contact.

This schedule is not a “marketing option”: it is a reliable control logic, especially in a Montreal urban setting where re-infestations and movement between units can happen.

A shock treatment is an additional or reinforced intervention based on the degree of infestation: massive infestation, spread across multiple rooms, a high density of hiding spots (clutter), presence in several complex areas (e.g. bed frame + living room + multiple baseboards). It is not supposed to be sold “by default”.

A good exterminator justifies it with on-site findings and adds it only if it genuinely improves control. If it is added, it must be justified, priced clearly and written up properly on the invoice.

You must require three things, without exception:

• A proper invoice: full company contact information, date, service address, description of the treatments, number of visits, and price.
• A written warranty on the invoice: a specific duration (e.g. X days/weeks/months) and the exact conditions to follow (preparation, access, washing, managing clutter, etc.).
• Clear and workable conditions: if it is not written clearly, the company cannot then fall back on a vague excuse to refuse the warranty. A serious warranty is a documented commitment, not a fuzzy sentence over the phone.

The cost depends on the number of rooms affected, the level of infestation, the type of home and the number of treatments needed. SOS Extermination offers a free quote in order to give you a clear price before the treatment.

They can come back if eggs hatch after the first treatment, if infested items are moved or if the preparation of the home was not followed. A follow-up helps reduce this risk. What to do after a treatment →

You generally need to bag certain fabrics, wash and dry the recommended items at high temperature, clear the areas to be treated and avoid moving infested items without protection. SOS Extermination provides suitable instructions before the treatment. The complete preparation guide →
